16-channel VME analog-to-digital converter VMEADC16
16-channel VME analog-to-digital converter
16-channels analog-to-digital converter VMEADC16 is intended for application in different systems for DC measurements. An analog part of the device is galvanically isolated from digital part. A low level of noises provides high resolution of ADC. An embedded microcontroller provides a simple interface and gives opportunity to improve characteristics of device in future by upgrading an embedded software. A detail description is here (14-НБТ-2003).
Parameters of VMEADC16:
